First of all there are subgoals with the first one being at 15k which is almost completed. Second of all a real peertube app is mandatory for its success, like they said 80% of people watching videos are from their phone. This app wont be a second way to watch peertube, for most it will be their entry into this ecosystem so it better be good.

I wouldn't want to associate with an app that's ripping off YouTube when you're an app trying to make a better YouTube.

But also, this is open source. Who are you to say that funding an effort should go to one place and not another? I think the people who actually put effort into Peertube are best place to determine what's good for the project.
